Name of the Vulnerable Software and Affected Versions
Linux kernel versions through 4.12.4
Description
The issue is related to a race condition in the fsnotify implementation. It allows local users to gain privileges or cause a denial of service, such as memory corruption, by leveraging the simultaneous execution of the
inotify handle event and vfs rename functions through a crafted application.Recommendations
For Linux kernel versions through 4.12.4, consider applying a patch or updating to a version that fixes the fsnotify implementation issue to prevent exploitation. As a temporary workaround, consider restricting access to the
inotify handle event and vfs rename functions to minimize the risk of exploitation. Found an issue in the description? Have something to add? Feel free to write us 👾
